IMPROVED COMPOSITION FOR PERCUSSION-CAPS, 800.

Specification forming part of Letters Patent No. 4Hh259, dated January12, 1864.

To all whom it may concern: Y

Be it known that I, HEINRICH Hoonsriir- 'lER, of the town of Langen, inthe Grand Duchy of Hesse, have invented a new and Improved ExplosiveComposition to fill Percussion-Oaps; and I do hereby declare that thefollowing is a full and exact description of the ingredients it consistsof and of the manner to compound them.

Take twelve parts of chloride of lead, eight parts of nitrate of potash,three parts gum-am- After having the nitrate of potash and gum-amberWell mixed, the chloride of lead is added and the Whole made into apaste with mucilage of gum-arabic (made by dissolving one part ofgum-arabio in ten parts of water) and granulated by rubbing it through ahair sieve. The mass is then carefully dried and pressed in the caps inthe usual manner. The

p I requisite quantity of the above mass for each cap, for military use,is three-fifths of a grain. After the mass has been introduced in thecap the same is coated with a varnish made ofnine parts alcohol and fourparts gum-shellac, or,instead thereof, covered with copper-foil, torender them water-proof.

What I claim as my invention, and desire to secure to my assignees, WM.0. LANGE and FERD. W. SENNEWALD, of St. Louis, Missouri, by LettersPatent, is-

, lhe application of chloride of lead, compounded as described herein,as an explosive mass for the ignition of gunpowder.
